Linter issue.
Even if you're not using one, you should be instinctively looking for a semicolon the moment you get a syntax error unless you're a complete beginner.
so the other day I sat down trying to setup a SSL cert for my self-hosted services
Have you heard of our Lord and Savior, Traefik + ACME issuers?
Let's encrypt brother
Let's Encrypt Expiry Bot just entered the chat.
Does Trafik also allow DNS based challenges with additional certbot plugins, or does it only work by serving a challenge in /.well-known/?
I’ve set up my internal homelab with LE certificates, but if I could get rid of certbot and do this automagically, it’d be nice…
I have it setup to use DNS challenges through Cloudflare, but it supports different providers as well. I just add the labels to my docker container and voila, I have TLS
Not all dns providers support acme, I've discovered to my recent annoyance. The one I use at work, for instance.
I already use certbot with my DNS provider, so it should generally be supported. And indeed, O found the docs, where all supported providers are listed.
Yeah. For wildcard DNS from letsencrypt, you can't do HTTP validation, only DNS, which involves creating a TXT record.
Your DNS provider needs to run an ACME server, which runs an API that'll add the required TXT records on request.
As I understand it.
The DNS provider needs to provide an API, but not an ACME server.
Your server contacts Lets Encrypt and wants a certificate - say for homeserver.example.com. It tells Let's Encrypt to use DNS based authentication. Let's encrypt answers with a challenge code, that you now publish as a txt record with a defined name via your providers API for this (sub)domain. Let's encrypt then checks the TXT record and if it finds the challenge there, it sends you the certificate.
Wouldn't the authentication API provided by your DNS host be the ACME server?
No, see also this diagram: https://www.digitalberry.fr/wp-content/uploads/2023/02/DNS-challenge-process.png
You use an ACME client (either explicitly with e.g. certbot or a webserver that has a client Iintegrated like Traefik, Caddy,...) to communicate with an ACME server (the CA, e.g. Let's encrypt). Your ACME client asks for a certificate with a DNS challenge. It gets a code that you/the client needs to publish as a DNS record. Only then the client talks to your DNS provider and tells them to put a specific TXT record on your domain (or onanual mode: the client prints out the value and you need to put it there manually). After your DNS provider published it, your client tells the server to check the challenge and hand you your certificate.
Your DNS provider in this diagram is just that one small rectangle in the lower left.
Note: There's nothing stopping your DNS provider to just do all of this, generate a certificate for you and providing you with a button in your account where you can download a certificate with a single click. Also if you are at a webhoster and only host a simple page there, they will probably also provide your with a TLS cert with the click of a single button.
Might want to check out swag from linuxserver.io
It's a docker/kubernetes container image with a working certbot client in it.
I don't like being on this picture.
Laying in bed thinking about the problem, "oh, that must be it!" Jump excitedly out of bed to work on the problem, "welp, that wasn't it."
I’ve been trying and failing to fix an email being sent to spam issue since last fucking Monday (with all the SPF, DMARC and DKIM garbage).
I want to die.
SPF, DMARC and DKIM
Ironically, spam generators are experts EXPERTS in this trash fire of a topic
Who is OP, and how did you get pictures of me last night?
LoL, blue shirt has no persistence. Anger and giving up gets you nowhere.

Title text:
40% of OpenBSD installs lead to shark attacks. It's their only standing security issue.
My friend just finished a couple solid days of debugging where there turned out to be a whole series of problems that looked like one bug, so even though he kept fixing things the app still kept not working. Finally hacked his way out of that jungle into the bright light of day.
Reminder to all you chaos monkeys: use [Object object] on web forms occasionally for a bit of fun.
Edit: and to remind typescript devs they’re just transpiling to JavaScript
I shit you not I got that object object response with a 200 status.
Aw come on, debugging can be fun. I love the investigative vibe of it. You get to be your favorite detective. You start asking around. You pin the the culprit. You get closer and closer to damning evidence. And then Bam! Fixed. Another mystery solved. Mine’s Columbo.
I love asking,
"What sick fuck thought this was an acceptable solution?"
And a few moments later:
"Oh. It was me."
Just finished with a refractoring project. I said this a LOT.
Agreed, for any non-trivial bug I just start dumping text into a word file to track what I'm doing. Like: error messages, values of variables at key places, libraries used, URLs of documentation and background reading and stackoverflow pages looked at, test fixes and their effects, etc. Then if someone asks me wtf I've been doing all day I can easily show them. Also, if I have the same problem a couple months later I can remind myself.
It's fun when you debug your own code.
Just later that day? Clearly, comic man doesn't have to cojones to fuck up as badly as I have.
I would be sad too, if someone broke my PC and smashed my home.
Is he giving himself cigarette burns?
Wow that's subtle. Good catch
Sure feels like that sometimes, LOL
My favorite so far:
$ gdb -ex 'file /bin/gdb'
run
corrupted double-linked list
Thread 1 "gdb" received signal SIGABRT, Aborted.
Every single day
Did the coffee mug go through the wall or up is ass?
Yes
Kinky

Why is he in his undies 😭😭😭
